汽轮机TSI轴向位移信号异常原因分析及处理

Turbine supervisory instrument axial displacement signal abnormal cause analysis and treatment

针对汽轮机安全监视系统(TSI)在安装完成后出现的轴向位移测点偏差大和周期性波动等问题,通过分析信号异常产生的原因,提出相对应的改造处理办法,有效保证了机组重要测点测量结果的准确性,提高了热工保护的可靠性。

Based on turbine supervisory instrument( TSI) axial displacement survey point deviation, periodic fluctuation andother problems after installation,by analyzing abnormal signal,reconstruction plan was indicated accordingly. Accuracy of unit important survey point was ensued. Reliability of thermal process protection was enhanced.
